The details of the door and window edging should be based on your requirements. Generally, the door and window edging is because the reserved gap of the hole is too large or the hole needs decoration, and an attached frame is added to the door and window frame.
It is a bit troublesome if you wrap the whole window through the hole, so the whole cost is very high. It is suggested to find a regular door and window company to remove all the original windows, install the hole and wrap the edge before installing the windows.
